Cleaning the Aluminum surface

The first step or secret to polishing aluminum is to clean and prepare the aluminum surface for buffing. This is very important and will make the work a lot easier.

Wipe all the grease, dirt, and debris from the surface and apply a solvent or degreaser. Also, check if any paint or finish particles are covering any part of the aluminum. If there are any, get rid of them with a stripper or sandpaper.

Sanding the aluminum

After the preparation, the next step is sanding the aluminum. Use sandpaper or a power drill with a wire brush attached to sand the aluminum.

Before sanding the aluminum, make sure you put on your safety gear like gloves and goggles. The waste aluminum particles can be harmful if inhaled or fly into your eyes. With your safety gears on, start by sanding the entire aluminum surface.

After that, sand the aluminum edges to make them sharp. This will ensure the aluminum surfaces and the edges have the same aesthetic feel after polishing it.

Sand any damaged or scratched areas. Ensure there’s no scratch and the entire aluminum surface is sharp and smooth before heading to the next step.

Cutting/Polishing the aluminum

Cutting or polishing aluminum may seem like a hard task, but it can be a lot easier with the right knowledge and guidance. Second, it is an inexpensive job.

Here, we’ll guide you on how to polish aluminum to be like chrome in your garage.

Small polishing task

If you have a small aluminum material to chrome, use a household item or home kit. Here are the ways and things used to polish your aluminum.

  • Get a clean and soft towel and toothpaste to buff out blemishes and scratches on the aluminum.
  • Get a bowl, baking soda, and water. Mix the baking soda and water in the bowl to make a paste. Rub the paste on the aluminum material and buff it in with a soft towel.
  • You can also create a polishing paste with vinegar and salt. This polishing paste will work fine on tarnish or light oxidation.
  • Another household item you can try is olive oil or lemon juice.

Larger polishing task

It is much better to do a polishing job on a large aluminum surface than on a small one. This is because you’ll need sanding disks and an aluminum wheel polishing kit, which will make it easier than using a hand. Sanding disks are available at any online or offline home improvement store. 

The disk should be around $30 to $50 for a pack of ten disks. However, the disks can wear out faster. So, replace the disks as soon as they become less effective.

To use the disk, get your drill, attach the disks to it, and set the speed to medium-high. The type of drill you want to use is your choice. For example, you can get a corded or battery-powered drill.

Submerge the disk in a bowl of water and leave it for some seconds or minutes. After that, attach it to a polishing pad. Then, start the polishing in a circular motion while maintaining moderate pressure. Do not apply much pressure for any reason. It could damage the surface you’re polishing.
